See for more details Gallery Plugin Also Simple Photo Gallery
It just takes all pictures in a given namespace and displays them as a gallery. github: https://github.com/splitbrain/dokuwiki-plugin-gallery
Syntax
A basic gallery can be added by selecting a namespace like this:
{{gallery>:namespace}}
All image files in the selected namespace will be added to the image gallery. Don't forget the “:” in front of the namespace.
Instead of using a whole namespace of images, you can also specify a single image – this makes more sense when combined with the lightbox mode (see below).
{{gallery>:namespace:someimage.jpg}}
The created gallery can be aligned by using white space (defaults to centered).
Here is a gallery of all Watchdog images in the MEDIA opencpn:manual:plugins:watchdog folder, using this code.
{{gallery>:opencpn:manual:plugins:watchdog?&lightbox}}
It may be useful for editors editing images. This shows all images under MEDIA in the :opencpn:manual:plugins:watchdog folder. This is different than just the images that are actually used in the documentation. The “lightbox”provided the javascript interface for clicking on an image and bringing it up in a separate window (browser dependent settings, so sometimes it does not work).
